CHINT Thermal Overload Relay (OVERLOAD) NXR-100 63gG, 100gG, 125gG, 160gG, 160gG Rated Current 23 – 100A

Function
NXR thermal overload relays (hereinafter abbreviated as thermal relays) are suitable for overload and phase loss protection for uninterrupted or intermittent AC motors with AC frequency of 50 Hz/60 Hz, a voltage up to 690 V, and a current of (0.1-630)A. The thermal relays also provide temperature compensation, action indication, automatic and manual reset, stop, and testing functions. The products are characterized by stable and reliable performance. The thermal relays can be plugged into contactors or installed independently.

Standards
IEC/EN 60947-4-1, IEC/EN 60947-5-1.
